Networked redundancy aircraft control system

Abstract

The invention provides a networked redundancy aircraft control system, and belongs to the technical field of aircraft control. According to the networked redundancy aircraft control system, multiple sets of similar or non-similar flight control computers are connected through a network by means of communication equipment in the system, comparison and decision making of control instructions are conducted by means of an arbitration unit on the network, and the appropriate instructions are selected to be output. In addition, in order to achieve supervision and redundancy processing of the arbitration unit, the system comprises a channel selection unit connected with the main flight control computer and the arbitration unit, the health states of the two units are judged according to heartbeatsignals of the arbitration unit and the main flight control computer, the reasonable instructions are selected according to the judgment result to control corresponding execution mechanisms, and meanwhile the units which work abnormally are reset. The networked redundancy aircraft control system can effectively improve the reliability and redundancy of the system.

Description

technical field

[0001] The invention belongs to the technical field of aircraft control, and in particular relates to an aircraft control system with network redundancy. Background technique

[0002] The basic function of the aircraft control system is to ensure the stable attitude of the aircraft through a certain control algorithm according to certain index requirements, and guide the aircraft to the desired position through a given control strategy to complete the established flight mission. At the same time, during the flight, the information exchange between the aircraft and the ground control station is realized.

[0003] At present, the aircraft control systems on the market are mainly aimed at the single-redundancy control of a single aircraft, which can better meet the installation and use requirements of small aircraft. However, for aircraft carrying high-cost reconnaissance / surveillance payloads, or even large and medium-sized aircraft that integrate reconnaissan...
